I don´t think that is right. As mentioned in the artikle on Warhammer-community, :
https://www.warhammer-community.com...n-the-new-edition-of-warhammer-age-of-sigmar/
the Skink Starpriest is a priest as well... : "U
nlike other Priests, they don’t have an innate prayer on their warscroll, so their newly granted ability to dispel endless spells and chant the Core Book prayers is an incredible boost."
And the Starpriests keywords includes "Star
priest" .
So maybe ( and Im not sure about this) The Skink Starpriest is a Priest and a Wizard as well? At least I couldn´t find a rule wich says Wizards could not be Priests.
Or the artikle on Warhammer Comunity was incorrect about the Starpriest beeing a Priest.
I.d.k.
